    Expand the brackrts and take the x's to one side then factor x out and divide
    Say I had (x+3)v=(x-1)u find x in terms of u,v.
    Then let log2=v log6=v. Remember you can times then out as they are just numbers. PM if you need any help.
    its okay, I get it now, someone explained it too me but thanks anyway, appreciate the help

    Yh I thought it was pretty low since i got 70 or 71/75 and if 67 was an A which is ridiculous then I wouldve got like 90UMS and not 94 or 96 Still annoyed i dropped marks for doing tanx=cosx/sinx
    oh well, 71 is still a really good score
    that's so annoying tho getting an identity slightly wrong
    did you get an A overall?

    its okay, I get it now, all I had to do was expand the brackets and collect like terms
    the answer was 3.52
    im getting as 1.5

    Does showing the method of finding coefficients of binomial expansion terms carry marks? I have the coefficients memorized upto n=12 so I was wondering if it would be ok to directly write down the terms.

    2ndly Also I know (a+b)^n - (a-b)^n = 2×sum of even terms of expansion and (a+b)^n×(a-b)^n = expansion of (a-b)^n except every power is doubled and such results. Can I directly write this result down without showing expansions?*

    when doing log questions- do we have to convert everything to base 10 or can we just use the log button on our calculator? i get the same answer its just much quicker to work out

    I just tried that Log question and got 3.52, not sure if the way I did it is odd though?

    (x+3)log2 = (x-1)log6

    then i divided by (x-1) and Log2 to get = (x+3)/(x-1) = Log6/Log2

    = (x+3)/(x-1) = 2.585

    (multiplied by x-1)

    = (x+3) = 2.585(x-1)

    expanded the bracket = (x+3) = 2.585x - 2.585

    subtracted x and 3 from the left side to get = 1.585x - 5.585

    = x = 5.585/1.585 = 3.52

    Is this how you guys did it?

    Btw if you have Casio Silver Calculator. Check your integrals in your calculators. Then you know if you got it wrong you will be able to change it!

    im getting as 1.5
    (x+3)log2=(x-1)log6

    0.301x + 0.903=0.778x-0.778

    0.903=0.477x-0.778

    1.681=0.477x

    x=1.681/0.477

    x=3.52

    240/300 is usually the lowest you can get for an A right? I'm so annoyed because I messed up the C1 exam so badly when it should've been an easy A for me....seriously made so many mistakes. So now I have the challenge of getting an A overall in AS Maths and have to get about 90% in C2 and S1 to do so

    For logs you get marks for working, so I recommend converting everything to base 10.

    I messed up in C1 so I need to get over 90UMS in both my next papers
    are there any specific papers you think I should try and any advice?
    294/300 is bloody amazing

    Depends what you got in C1 tbh. Aim for 100. Yes 240/300 is the lowest for an A.

    C2, even if you do all the papers. Do the gold papers again. Do solomon papers. In the real exams I finshed considerably early. Set work out clear so its easy to check(came into use in C1 last year as I noticed a mistake in my surds!). Make sure you py special attention to mark schemes as every mark counts. Tbh it is all just practice and that is it!

    Haha, Indeed we are, I'm not worried about getting 90% in S1 as it's my last exam and have plenty of time to just focus on it. Whereas next week I have 4 exams in a row including C2 so I'm going to smash C2 like crazy tonight, we can do this!
